Value ofVR-CT in the evaluation of laryngoceles and trachealdiverticulum

Laryngocele and tracheal diverticulum are uncommon conditions that represent a bening sacculation of the upper airway with air content.Historically, x-ray studies with oral barium have been the most common technique for their detection and evaluation.However, CT has became a widely used technique for these tasks, due to its availability and extensive anatomical information.MDCT allows MPR and VR reconstructions that improve lesion detection and make easier for the clinician to understand anatomical relationships.
